Abstract—A new calibration procedure was proposed for strap down inertial measurement unit (IMU) in a body reference frame which was independent of the turntable. The proposed methodology required no precise mechanical platform for the calibr

使用四元数计算各个时刻的姿态数据，并能在欧拉角和四元数，旋转矩阵之间转换，通过地磁数据校正陀螺仪算出的姿态。MADGWICKAHRS Implementation of Madgwick s IMU and AHRS algorithms-MADGWICKAHRS Implementation of Madgwick s IMU and AHRS algorithms
